Question

当我尝试从jinja模板传递多个参数时，我遇到了解析错误：

jinja2.exceptions.TemplateSyntaxError：期望令牌'，'，得到'：'

@classmethod
def follow_user(cls, followed_email, follower_email):
    with CursorFromConnectionFromPool() as cursor:
        cursor.execute('INSERT INTO connections(follower_id, followee_id) VALUES (%s, %s)',
                           (follower_email,followed_email))
@classmethod
def unfollow_user(cls, followed_email, follower_email):
    with CursorFromConnectionFromPool() as cursor:
        cursor.execute("DELETE from connections WHERE follower_id = '{}' AND followee_id = '{}' ",
                           (follower_email, followed_email))

{% if is_following %}
 <a class="btn btn-danger" href="{{ url_for('user.unfollow_user',followed_email:followed.email,follower_email:follower_email) }}" role="button">Unfollow</a>
 {% else %}
 <a class="btn btn-success" href="{{url_for('user.follow_user',followed_email:followed.email,follower_email:follower_email) }}" role="button">Follow</a>
{% endif %}

Answer 1

这一行：

<a class="btn btn-danger" href="{{ url_for('user.unfollow_user',followed_email:followed.email,follower_email:follower_email) }}" role="button">Unfollow</a>

应替换为：

<a class="btn btn-danger" href="{{ url_for('user.unfollow_user',followed_email=followed.email,follower_email=follower_email) }}" role="button">Unfollow</a>

并在第二行使用相同的'='：

<a class="btn btn-success" href="{{url_for('user.follow_user',followed_email=followed.email,follower_email=follower_email) }}" role="button">Follow</a>

将参数传递给url_for中的参数时，您应该使用=。
